Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine for machining mechanical parts. Background Art

[0002] Polishing machine is also called grinding machine, which is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. The speed of the polishing disc is generally 1500-3000r / min, most of which are stepless speed change, and can be adjusted at any time according to the needs during construction.

[0004] When the above-mentioned polishing machine for machining mechanical parts is working, since the dust suction mechanism sucks away the dust and debris left on the workbench during machining, the staff needs to press the ball on the sliding rod to make the ball leave the slot and pull the sliding rod up and down along the sleeve. The direction of the suction hood can be adjusted by rotating the rolling bearing. The staff needs to spend time adjusting the angle and height every time, which will seriously affect the work efficiency, especially when frequent adjustments are required. Manual adjustment of the angle and height may pose certain safety hazards. Utility Model Content
